' 'A praisalhumanita-ai, 1-9-52. saw no; a a;

T0,; mllwipomjt came a; Be it known that I, NTZILLIA'MQG. Harp rons, a citizen of the United States, residing, at Cleveland, in the county of 'Cuyahoga and State Ohio, have invented certainircwand useful Improvements'in -111- dow Screens, of which the followlng 41s a Sp efcification.

My invention relates to iiirprovements in window screens, and specifically, to'thfe sliding type of screen wherein the sliding sashes are adapted to have [screen members secured thereto, the movement of "these screen members to be controlled by the rai s- =111g'; 2L11 Cl lowering .of the sliding sashes, and

building and in alinement with the upper and. lower ends of the windowffra-me for receiving the screens therein, when the windows are in a full, or partially closedposii e'- a a a An object of the invention resides in the provision of an improved coupler whereby a window screen may b readily attached to or detached from a sliding sash in a novel and expeditious manner for allowing the sliding sash to be operated without occasioning an operation of the screen, and for further allowing the screen to be removed from the window frame, for repairing, etc.

lVith these general objects in View and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claim. a

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is an elevation of a window casing together with the sliding sashes there in, a portion of the building wall being broken away for more clearly disclosing the position of the screen members with respect to the sliding sashes.

Figure 2 is a vertical cross sectional view of the structure shown in Figure 1.

Figure 3 is a detail, fragmentary enlarged sectional View of the upper sliding sash having the upper sliding screen connected thereto.

Figure 4 is a vertical sectional view upon the line 4-4 of Figure 3, and

is a viewsimilar to'Figure 4,

a but taken upon the line 5- 5 ofFigure-li,

fliefer ring" to the the building wall A. is shown as having f'ormed "or otherwise disposed therein, a window rains B havingthe usual upper and lower jslidin'g sashesther'ein as "(l and D respecely- ,.l a a .v

' The'build in'g wall is so constructed as to form an upper and lbwer pocket 1 and 2 therein, which pockets are in ali-nement with the upper and lowerisills of the window am s more clearly'shown in Figure's 1 ands. The "lower 'framehar it of are 'i w rsliding Sa an isladapted a have close contact with theupper framebarof a substantially rectangular j screen member 3 and pivot'ally secured centrally upon this fram bar of o f the said sash is'a "link 4, which linkis ofangfufllar formation as more clearlygshown in Figure so as aexaaa inwardly upon the projecting edge the frame bar d and thence downwardly and having a circular shaped plate or head portion 5 thereon. It is of course to be understood that the thickness of the frame of the screen 3 is less than that of the frame bar d of the sliding sash D so as to allow the outer surface of the screen to be flush with the outer surface of the window frame so as to permit the inner portion of the window frame to project beyond the adjacent surface of the screen so as to allow this projecting portion of the window frame to contact with the window sill as shown in Figure 1. Set with a mortise in the upper frame bar of the screen 3 is a substantially rectangular plate 6, which plate is sodisposed as to lie substantially beneath the pivoted link 4 of the frame bar d of the lower sash. This plate 6 is suitably cut away as at 7 for allowing the disk or head 5 of the link 4 to snap therein as shown in the figures, for effectively connecting the screen to the sash whenever it is desired that the screen be raised or lowered with the raising or lowering movement of the sash, The head or disk 5 of the link 4 has formed thereon, a relatively small projecting finger 6 for readily allowing this disk to be disengaged from the opening in the plate 6.

The upper sliding sash C also carries a screen 3, the bottom frame bar of which, normally rests upon the upper frame bar of the sliding sash and when connected to the sash in a manner hereinafter described, the

5" of the link 4.

same is adapted to slide out of and into the pocket 1 whenever a sliding movement of the sash is occasioned. Referring to Figure,

V appreciated that the headed or disked end 5 of the link a may be snapped into the opening in the plate 6 for rigidly connecting the said screen to the sash.

The height of the lower screen 3 is rela,

tively greater than the height of the upper screen 3 and it is of course to be understood that suitable slots are provided in the upper and lower sills of the B for permitting of a sliding movement of these screens into their receiving pockets 1 and 2. The lower screen 3 when connected to the sash D functions as a usual window screen when this sash is raised and the upper screen 3 cons'tltutes a ventllatmg screen when the sash C 1s moved to a position subhas a suitable opening formed slot, and

window frame stantially as shown in Figures 1 and 2. In view of the detachable coupling means between the screens and sashes, it will be seen that the sashes may be readily raised or lowered without occasioning an operation of the screens and further, by releasing these catches, the screens may be readily removed for rewiring, etc.

WVhat I claim as new is In combination, a frame, a pair of slidable sashes in the frame, a coupling comprising a plate embedded in the face of one sash to be flush therewith, and having a slot leading in from one of the side edges there- 'of and provided at its inner end with a circular enlargement, a second plate embedded in the face of the other sash to be flush therewith, and a link pivotally mounted upon th second mentioned plate and having a head adapted to seat in the enlargement of the a shank adapted to seat in the outer portion of the slot, said link completely filling the slot and the enlargement thereof, and the outer surfaceof the link lying in the same plane as that occupied by the outer surface of the slotted plate, when the link is engaged in the slot and the enlargement thereof.

In testimony whereof I aflix my signature.
